Description

Patent Descriptive Report for "VEHICLE WITH A SLIDING DOOR".

The present invention relates to a vehicle, in particular a motor vehicle, with a bodywork, a sliding door and a centering means that is releasably connectable with a traffic jam.

The sliding door comprises a guide rail and a sliding carriage which is movably mounted longitudinally on the guide rail and which is connected to the body by a multiple joint. Centering means is provided at the end of the sliding door away from the multi-joint. Centering means can be provided on the sliding door. In this case, the centering means is freely connectable with a body-supplied jam. It is, however, also possible that the centering means is provided in the bodywork. In this case, the centering means can be releasably connected with a counter provided in the sliding door.

A sliding door of the type mentioned above is known from DE 10 2008 016 650 B3, which is expressly referred to herein. In this sliding door, the multi-joint comprises a hinge bracket which is rotatably mounted on the sliding carriage and a body flange, and a control lever which is rotatably mounted on the sliding carriage and one or the body flange. The prior art sliding door further comprises a first intermediate lever which is rotatably mounted on the control lever and a second intermediate lever which is rotatably mounted on the first intermediate lever and sliding carriage. At the far-away end of the multiple joint, the sliding door is rotatably and longitudinally mounted by a centering means. It can be locked there. The control lever includes an extension in which the first intermediate lever is rotatably mounted. At the connection joint of the first intermediate lever and the second intermediate lever, a guide pin is provided which is guided into a guide provided on the sliding door. The guide extends inclined with respect to the guide rail. The guide extends outwardly in a direction away from the hinge bracket.

Another sliding door as mentioned above is described in EP 2 008 846 A2, which is also referred to herein expressly. Here a drive rod is present which is rotatably mounted on the control lever. At the far-away end of the multi-joint, the sliding door is rotatably and longitudinally movable mounted by a centering means. It can be locked there. The drive rod is rotatably mounted on the guide rail. The control lever includes a lever arm on which the drive rod is rotatably mounted. The intermediate lever is provided with a guide pin, which is guided in a guide provided on the sliding door.

It is the object of the invention to propose an improved sliding door of the type mentioned above.

According to the invention, this object is achieved by the aspects of claim 1. This solution is characterized by the fact that a backstop and / or centering means are provided in the roof region and in the bodywork sill region. This can improve vehicle stability in the closed position of the sliding door.

Advantageous developments are described in the subclaims.

tions.

Advantageously, the body does not include a column in the sliding door portion facing away from the multiple joint. When the sliding door is used, for example, as the tailgate of a motor vehicle, when the multi-joint is provided in the column C region and when the sliding door can be opened to the rear, it may be advantageous when no column B is present in the bodywork.

In the closed position, the sliding door is then retained in the ceiling region and in the threshold region by the counter-centering means. Since the body column is absent at the sliding door end away from the multi-joint, that is, since particularly column B is absent, the access opening for the vehicle may be substantially increased. In particular, wheelchairs or the like may be moved more easily or completely within the vehicle or may be removed from the vehicle. However it is possible to use a sliding door of the type mentioned above.

In the roof region and in the threshold region a counter-centering and centering means are present. It is possible that the backrests are supplied in the bodywork and centering means are provided in the sliding door. However, it is also possible to provide sliding door jams and body centering means. Finally, it is also possible to provide one or two bodywork jam and the other sliding door jam. The centering means are then disposed in the other part.

In certain cases, it is advantageous when a backstop is provided in the body roof region and a backstop is provided in the body sill region. According to another advantageous development, one or both

The jams include a guide to the centering medium. Centering means is guide in respective guide. The guide may be formed as a guide channel.

Another advantageous development is characterized in that one or more centering means includes a centering pin. The centering pin may have a circular cross section.

Advantageously, the counterbolt motion curve differs from the centering medium motion curve. In this way a sliding door lock can be produced. Another advantageous development is characterized by the fact that

which at the end point of the counter movement curve corresponds to the end point of the center curve movement curve. Then no sliding door interlock is produced at the end point of the motion curves. Due to the deviation of motion curves in the vicinity of the end point, a sliding door interlock is produced by leaving the end point, which retains the sliding door at the end point. This interlock generates a resistance for opening the sliding door. In this way a stable position of the sliding door can be obtained at its end point.

One embodiment of the invention will be explained in detail below with reference to the accompanying drawing. In the drawing: Figure 1 shows a prior art sliding door for

a motor vehicle in the closed position in a schematic view from above;

It is opened at the far end facing away from the hinge bracket 7, ie its front inner end in this embodiment. On a body flange 15, which is fixed to column B 2, a hinge bolt 16 is provided which engages with the U-shaped receptacle 14. In the fully closed position of the sliding door as shown in Figure 1, the pivot bolt Lation 16 is located at the bottom of the U-shaped receptacle 14. It can be locked there (not shown in the drawing).

Control lever 11 includes an extension 22 extending out of joint 12. Extension 22 extends control lever 11 along the connection line of joint 13 to joint 12 beyond joint 12. Extension 22 is slightly curved outward and backward, respectively, with respect to the connection line between joints 13 and 12, ie in the longitudinal direction of control lever 11. At control lever 11, joint 17 for first intermediate lever 10 is provided in the outermost region of extension 22.

In connection joint 20 of first intermediate lever 10 and second intermediate lever 18, a guide pin 12 is provided which is guided in a guide 24. Guide 24 is provided in sliding door 1. Correspondingly guide 24 It is a guide firmly mounted on the door. It extends inclined with respect to guide rail 5 in a direction away from the hinge bracket 7 outwards. Guide 24 is continuously linearly configured. Its inclination is the same along its entire length. In the fully closed position of the sliding door 1, which is

shown in figure 1, the hinge screw 16 is in the U-shaped receptacle 14, i.e. in the region of its end. Guide pin 23 is located in the region of the rear inner end of guide 24. First intermediate lever 10 points forward and inwardly of gasket 17. Second intermediate lever 18 points rearward and inwardly of gasket 19 .

In the course of the opening movement, the position as shown in figure 2 is traversed. This opening movement can be generated whereby the guide rail 5 is moved to the rear with respect to the slide carriage 6. In the slide carriage 6 a motor, in particular an electric motor, can be provided to drive the slide rail. guide 5 with respect to sliding carriage 6. Instead of or in addition a motor, in particular an electric motor, can be provided to drive the hinge bracket 7 and / or the control lever 11. Advantageously, a A motor for driving the hinge bracket 7 and / or the control lever 11 is provided on the body flange 4 or some other body part.

The opening movement can, however, also be generated manually instead of or in addition. In particular, the guide rail 5 can be manually moved to the rear with respect to the slide cart 6. For this purpose, a handle or several handles may be provided on the sliding door 1, whereby the sliding door 1 and with the same guide rail 5 can be moved relative to the slide cart 6. The handle can be provided at the inner front end of the sliding door 1 and / or at the outer front end of the sliding door 1 and / or the rear end exterior of sliding door 1. Sliding part 1 can be opened and also closed again by applying force to each of these three points.

Without the guide pin 23, the slide carriage 6 could be moved freely on the guide rail 5. The guide pin 23 guided in the guide 24 prevents this free travel capability and defines the relative position of the slide carriage 6 with respect to the guide rail 5 and thus with respect to sliding door 1. This is done on guide parts 24 which have a non-zero inclination with respect to guide rail 5, i.e. they do not extend parallel to the guide rail. Guide 5. Guide 24 has the same nonzero inclination with respect to guide rail 5 along its entire length.

When guide rail 5 is moved to the rear with

With respect to the sliding trolley 6 by motor or manually, the guide pin 23 guided in the guide 24 moves outward with respect to the guide rail 5 and the sliding trolley 6, where the second intermediate lever 18 is inclined clockwise around the gasket 19. By moving the guide pin 23 with respect to the slide carriage 6 to the rear and outward, the joint 17 located at the other end of the first intermediate lever 10 is also moved to the rear, where the locking lever. Control 11 is rotated around the joint 12 counterclockwise. The control lever 11 thus tilts counterclockwise around the joint 13 on the body flange 4. By tilting the control lever 11, the hinge bracket 7 is also angled counterclockwise around the joint 9. The joint plate 21 of the slide carriage 6 is also forcibly guided by tilting the hinge bracket 7 around the joint 9, provided it forms a multiple joint with the hinge bracket 7, the control lever 11 and body flange 4 - as explained above.

The actuation movement to open the sliding door 1 may, however, also be initiated in some other way, in particular by a motorized and / or manual actuation of the hinge bracket 7 and / or the control lever 11 and / or the first intermediate lever 10 and / or the second intermediate lever 18 about one or more of the joints 9, 8, 13, 12, 17, 20, 19.

The fully open position of the sliding door 1 is shown

The first intermediate lever 10 has been inclined clockwise around the joint 17 with respect to extension 22 by about 90 °. The guide pin 23 has reached the front closed end of the guide 24. The second intermediate lever 18 has been inclined clockwise around the joint 19 with respect to the slide carriage 6 or the joint plate 21 by about 45 °. The opening angle of the intermediate levers 10, 18 at joint 20 has been increased from about 30 ° to about 150 °. Control lever 11 and slide bracket 7 have been angled 120 ° in a counterclockwise direction around joints 13 and 9. When sliding door 1 is to be closed, the sliding positions

Crites are traversed in reverse order. The closing movement of the sliding door 1 may be effected wherein the guide rail 5 is moved forward by motor and / or manually with respect to the slide carriage 6. The relative movement of the guide rail 5 is transmitted by the guide 24 to the guide pin 23 and thereafter inserted into the multiple joint described by the first intermediate lever 10. It is also possible, however, to initiate the closing movement in a manner which has been described for the opening movement.

In Figures 1, 2, 3, the paths of the front end 25 and rear end 26 of the outer door panel 27 are shown. The front end 25 of the outer door panel 27 initially moves at an angle of about 30 ° with respect to the longitudinal axis of the vehicle to the rear and outwards. The inclination angle of the U-shaped receptacle 14 corresponds with this angle. Subsequently, it describes an arc with a larger radius, the end of which 28 includes a tangent extending parallel to the longitudinal axis of the vehicle. The rear end 26 of the outer door panel 27 initially moves at approximately right angles away from the body and then describes a narrowed arc to an end point 29 which is substantially the same distance from the vehicle body as the point. end 128 of front end 25.

Figure 4 shows a sliding door 41 and associated body parts 42, which are formed differently than in the embodiment of figures 1 to 3 in a perspective representation. The multi-joint is provided at the rear end of the sliding door 41. It is connected with body C column 43 of the body 42. At the end of the sliding door 41 away from the multi-joint a counter 45 is provided in the roof region 44. Mounting 45 is mounted on a ceiling rail molding 46. It is located in the lower region of the ceiling rail molding 46.

In the sill region 47, an additional jam 48 is provided. The counter 48 is disposed in a floor frame 49. It is located in the upper region of the floor frame 49. At its upper end strip 50 the sliding door 41 includes

includes a centering means 51 that cooperates with the counter 45. In its floor panel 52 the sliding door 41 includes a centering means 53 that cooperates with the counter 48. The centering means 51, 53 are located at the front end of the door 41, that is, at the end of the sliding door 41 away from the multi-joint. Body 42 does not include a B column.

Fig. 5 shows the counter 48 and centering means 53 of Fig. 4 in an enlarged schematic representation from above. The counter 45 and the centering means 51 are formed in the same manner.

The counter 48 which is provided on the floor frame 49 of the body 42 comprises a guide 54 which is formed as the guide channel. Centering means 53, which is provided on sliding door 41, includes a centering pin 55. Centering pin 55 has a circular cross section. The width of the guide 54 substantially corresponds with the diameter of the centering pin 55.

Figure 5 shows the terminal position of centering pin 55 in the

guide 54, which is taken by the centering pin 55 with the sliding door completely closed 41. The centering pin 55 is then located at the front end of the guide 54.

In Figure 5, the motion curve of the guide 54 is provided with the reference numeral 56. It follows the center line of the guide 54.

In Figure 5, the movement curve of the centering pin 55 is provided with reference numeral 57. This movement curve is determined by the mechanics of the door, that is, by the position and dimensions of the joint, the guide rail. , the slide carriage and the centering pin 55. If the centering pin 55 was not attached to the guide 54, it would pass through the motion curve 57 with the movement of the sliding door 41. As shown in figure 5, the motion curve 56 of the guide 54 of the counter 48 48 differs from the motion curve 57 of the centering pin 55 of the centering means 53.

Due to the guide 54, the centering pin 55 is forced into the bend

56 of the guide 54. It is forcibly guided in the motion curve 56 of the guide 54. This results in a jam leading to a corresponding deformation of the sliding door 41.

As is also shown in Figure 5, the end point 58 of the motion curve 56 of the guide bar 54 of the counter 48 corresponds with the end point 58 of the motion curve 57 of the centering pin 55 of the centering means 53. The end point 58 corresponds to with the position of the centering pin 55 in the fully closed position of the sliding door 41. In this fully closed position, the sliding door 41 is therefore not jammed and deformed.

When the sliding door is to be opened from its fully closed position, the centering pin 55 is moved to the rear in the guide 54. Since the motion curve 57 differs from the motion curve 56, a jam and, therefore, deformation of the sliding door 41 is generated by this movement. The energy expenditure required for this purpose stably holds the sliding door 41 in its fully closed position. Must be overcome at opening of sliding door 41.

At the opening of the sliding door 41, the centering pin 55 runs the guide 54 towards the rear until it leaves the guide 54 through the guide 59 aperture 59. The guide opening 54 of the guide 54 is shaped like a Funnel In closing the sliding door, the reverse path is traveled.

Due to the funnel-shaped design of the opening 59 it is ensured that the centering pin 55 can be safely inserted into the guide 54 at the closing of the sliding door 41.
